The study, published March 23 in the journal "Facets," looked at the B.C. government’s list of threatened, special-concern and secure species and found only 14 species saw genuine improvement in their status between 2008 and 2025.

There were population increases for the hairy woodpecker, humpback whale, the broad-winged hawk and long-billed curlew, the study says. 

The researchers defined changes in species' risk status as "genuine" when they reflected trends in population or size. 

For example, dragonfly populations of blue dashers, western pondhawk and black saddlebag improved as warming temperatures increased their range. 

An additional 14 species changed for the worse, like the monarch butterfly and the bobolink, whose status reflected population declines and increasing threats. 

B.C. lists 493 species in the endangered "red" category, and 1,233 in the vulnerable "blue" category, representing a 25 per cent increase from 2008 that is mostly due to the addition of species on the list. 

Peter Thompson, the study's co-author and a post-doctoral researcher at Simon Fraser University, said the most common pattern was for nothing to change at all. 

"So, if a species was put on the red list in 2008, which is the highest category of endangerment, the most likely thing is it's still on the red list as we speak today," he said. 

Thompson said the B.C. government's database has collected an "impressive" number of new species over the past 20 years, but not enough is being done to help those that are threatened or endangered. 

B.C. is the most biologically diverse province in Canada, meaning it has the largest variety of species and ecosystems. 

Only about one per cent of the province is covered by Canada's Species at Risk Act, which is meant to protect species on federal land. 

The rest receive some protection from the provincial Wildlife Act, but only four species have been listed since its inception in 1996: the sea otter, burrowing owl, American white pelican and Vancouver Island marmot. 

"It's not necessarily what protections are offered that's the problem, it's the spread of species," Thompson said. "A lot of the creepy-crawlies, the insects, the little guys, the invertebrates that we don't know very much about are being left behind." 

He said researchers documented more than 900 "ghost species," that are known to be at risk but haven't been placed on the list, and many of them are arthropods such as spiders. 

Dedicated legislation could help fill in the gaps that exist with the Wildlife Act and other B.C. laws that provide some measure of protection for species, Thompson said. 

The study noted the Wildlife Act doesn't set out legal requirements for habitat protection, recovery planning or timelines. 

It also suggests there is an overreliance on non-profit land trusts and stewardship efforts, which the authors say results "in uneven and geographically patchy protection."

Thompson said he'd like to see proactive efforts to improve the status of at-risk species before they're at the brink of extinction. 

"They are still in serious trouble and they still need our help. And that's not an entirely surprising finding to us, but it's really important to quantify that, to put it on paper, and to continue raising the alarm that more help is needed for endangered species here in B.C. and across Canada."
